MOUNTING FOR WHEELS AND AXLES OF MINE-CARS.

Application filed July 13, 1915.

To all whom it may concern Be it known that I, VVAL'rnn A. Donsnr, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have .invented certain new and useful improvements in lrlountings for Wheels and Axles of Mine-Cars, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in devices for mounting the wheels and axles on the cars that are used in coal mines; par ticularly to improvements in such mountings whereby the axles and the wheels, proper, will be relieved of strains and wear, and the latter, and the loss caused by them, will be taken by cheap easily replaced parts.

Figure l is a cross section of a coal mine car having axles, wheels and monntingsembodying my improvements.

Fig. 2 is a vertical cross section on the line 2-2 of Fig. 1.

Fig. 3 is an end view of a bushing.

Fig. 4 is a longitudinal section of the same.

Fig. 5 is an end view of one of the wheels detached.

In the drawings 1 indicates the axle. It is formed so as to have no engagement with either of the boxes or either of the Wheels such as will transmit to them thrusts from the car or its load that is to say, it has none of the usual shoulders or collars in trans verse planes immediately adjacent to those of the inner ends of the boxes. It can be made with minimum expense by cutting it from round rods of metal of suitable diameter and of the required length. 2, 2 indicate the hearings or boxes in which this shaft is loosely mounted, and the latter (although also mounted loosely in the wheels) can if circumstances compel it to, rotate in the boxes. The shaft can be passed freely longitudinally through the boxes, transversely of the car, when made of materialsuch as above spocified' Each of the bearings or boxes 2 has horizontal flanges G integral therewith which are secured to the ca r by bolts or rivets 18.

The car may be built with the ordinary frame bottom and side walls of wood; but I prefer to build the body part upon a metallic framework such as I have shown in my application Serial No. 37,086, filed June 29,

1915. 4, 4 indicate the metallic bottom sills upon which are laid the planks 3, and to which are secured the side walls 5.

9, 9 indicate the wheels with treads adapted to rest upon the rails 19, and with flanges 20, respectively inside the rail treads. Each wheel is cast with a tubular huh 8 having an integral oil chamber 15. Within each hub there is a bushing 12 which fits the end of the shaft 1 snugly and also fits inside of the wheel hub 8. The inner end of the bushing is formed with projections or lugs 13, preferably of the nature of sections of a circular peripheral flange. The inner end of the wheel hub S is formed with recesses 11 of a peripheral length slightly greater than that of the projecting flange sections 13. hen the bushing is in place these projections fit in the recesses in the end of the hub and the hub and the bushing abut and engage each other by circumferentially presented shoulders, and the bushing and hub are locked together, so that the former rotates with the wheel. But the inner end of the bushing ears against the flange 7 at the outer end of the box.

At each end of the axle there is a detachable device such as a pin, bolt or cotter 17, and between each of these and the adjacent wheel there is a wearing washer 16.

The lubricant in the chamber 15 passes to the inner wearing surface of the bushing through the passages or ports 21, and from these it is carried along the axle to the endthrust surfaces of the bushing.

it will be seen that under ordinary circumstances and while the car is moving in straight lines each wheel, with its bushing 8, rotates upon the end part of the axle. if at any instant there is a slight cramping Of the bushing against the axle the latter can rotate in its bearings. It will also be seen that if the track swerves from a straight line the flange 20 of that wheel which is on the outer curve begins tobear against the rail tread 19, and the inertia of the car and its load transmits pressure through the box of said wheel to its bushing and it is trans mitted thence through the wheel to the rail. The axle having no engagement, along axial lines, with either that wheel or its bearing there is no wear at places other than the wearing surfaces of the bushing of the wheel. That is to say, the more expensi elements of the structure are relieved, and the Wear is all taken by easily replaceable parts of minimum cost.

\Vhat I claim is:

1.. The herein described wheel mounting for a coal mine car having in combination with the car body and the bearing boxes secured thereto, the axle mounted loosely in the said boxes and free of longitudinal engagement therewith, the Wheels, and the bushings in the hubs of the Wheels an d having circumterentially presented shoulders whereby they are separably locked to the hubs of the Wheels, thesaid bushings being arranged to bear against the outer ends oi the said boxes respectively.

The herein described wheel mounting for a coal mine car having in combination the car body, the bearing boxes secured thereto, the axle formed of round rod mounted loosely in said boxes and adapted to be passed longitudinally therethrough, the Wheels formed Withhubs having recesses or sockets, the bushings having lugs or pro- 3. The herein described Wheel mounting for a coal mine car having in combination a car body, the boxe'seach formed with an integral bearing tube and secured to the body, the cylindrical axle rotatably mounted inthe said boxes and adapted to be passed longitudinally theretln'ough, the Wheels each formed w ith a hub havingsockets or recesses at its inner end, and the bushings within the hubs each having one or more lugs or projections detachably seated in said sockets or recesses, and arranged to bear against the outer ends of the said boxes, substantially as set forth.

In testimony whereof, I ailix my signature, in presence of two Witnesses.
